Could you try exporting/importing a single contact, and see if that works?

Since you can import into Outlook, have you tried exporting from Outlook into Gmail? Or tried doing a single contact in a .csv file, as @VidarS.Ramdal suggested? It sounds like there's some issue with your source file.

@VidarS.Ramdal Per your suggestion, I cut down the .csv file to a single contact and imported it. It worked.

That's probably good news. Then the problem is with either one (or more) of your contacts, or the number of contacts. You could try exporting/importing 50% of your contacts, and try again. If that works, try with 50% of the remaining contacts and so on. If there's a problem, reduce the set until you have found the troublesome contact(s), which you can then remove manually.

Can you summarize the information at the link, please. If the link goes dead, the answer won't be able to stand alone.

I am not sure how #4 is relevant. the data was exported from Thunderbird and it does have headers.

open the exported file in a simple text editor and see if it is really plain text. I have seen people think they are creating a text file bit is really something different. Another thought is at the end of each record there probably should be a carriage return and a line feed... (these are usually hidden unless you look at a files actual characters)
